As previously announced, the company successfully completed a flow test program in June on the three largest production wells at the WGP Geysers project in northern California confirming that the wells were still open and ready for production. GeothermEx Inc. (a Schlumberger company) designed the isochronal (step-rate) flow test program, and monitored the testing of the wells.

GeothermEx reports that the four production wells are capable of delivering an initial capacity of 28.1 MW (gross) or 25.4 MW (net) based on current power plant steam conversion rates from a detailed design for a 28.8 MW (net) power plant.
